import (
"fmt"
"strings"
)This script imports fmt and strings packages.
fmt.Println(strings.ToUpper("programming"))
// Output: PROGRAMMINGIn this example, we passed a string into the ToUpper() function that converted the programming word into uppercase.
In the above example, we passed a single word. Now let’s pass a phrase to check if a function works with a phrase or not.
fmt.Println(strings.ToUpper("programming is easy"))
